Indurating Machines

Conveyor-type indurating machines are used for the production of pellets for various purposes: fluxed and non-fluxed pellets are used for metallization and blast furnace production, non-ferrous metallurgy and Ferroalloy production. Processed raw materials include hematite and magnetite concentrates, iron ore concentrates with high content of sulfur and silica, titanomagnetites with a high content of vanadium, oxide and carbonate manganese ores, copper-and-nickel concentrates, etc.

Key characteristics:

Process area, m²	52 - 1000
Raw pellets layer width, m	1,5 - 4,0
Raw pellets layer height, m	up to 0,55
Pellet car travel speed, m/min	0,6 - 8
Specific output, t/(m² х hour)	0,9–1,3

Linear Sinter Coolers

Linear sinter coolers are conveyor-type devices with a continuously moving conveyor chain, continuous hot sinter loading, sinter cooling by blowing air through the sinter layer, and discharging it via a discharge tray.

Key characteristics:

Cooling area, m²	up to 450
Effective width, m	up to 3,5
Sinter layer height, m	up to 1,5
Cooler incline, degrees	up to 16
Output, t/h	up to 1000
Charging sinter temperature, С^o	up to 850
Sinter output temperature, С^o	up to 100

Linear cooler advantages: *

Effective placement of sinter on the belt (larger pieces are placed in the bottom layer, then the fine fraction and the average fraction is placed in the top layer uniformly over the belt width). No special feeder required; sinter is loaded via a tray with self-lining and minimum height difference.

Simple in configuration (straight) guides that increase durability of rollers and guides.

Can be installed at an angle to the horizontal. Ability to raise sinter to needed level for further processing: primary sorting, additional crushing etc. without using additional conveyors and special mechanisms. Allows reducing the overall height of the sinter plant and the total weight of equipment.

- Linear coolers, due to their shape, can be more effectively combined with other technological and service equipment: conveyors, blowers, lifting devices.

Occupies much smaller area.

Relatively low cost for repair because of simple construction.

The removal of sinter spilled under the linear cooler is performed by a simple linear conveyor without stopping the cooler operation.

Sinter unloading doesn’t require additional mechanisms like feeders, special conveyors, and other equipment.
